Live tweets and updates from the preliminary hearing of Aurora theater shooting suspect James Homes. Prosecutors and defense are expected to lay out much of the evidence they have to determine if he can stand trial.

Police reports from the day of the Aurora theater shooting noted suspect James Holmes "stared off into space" and "seemed out of it" as Aurora police officers took him into custody.

Officer Jason Oviatt, who discovered Holmes behind the Century 16 theater on July 20 was first to testify in the preliminary hearing Monday. Oviatt noted that Holmes understood direction and fully complied with officers.

"He was very relaxed," Oviatt testified. "It was like there weren't normal emotional responses."

The officer said they found the man later identified as Holmes with hands on top of his car, next to a semi automatic handgun.

Holmes said little but seemed to understand questions and instructions he received and cooperated with officers.
